TUBE FRAME FOR AXMINSTER LOOMS.

Application filed December 27, 1923.

To all whom t may concern.'

Be it known that I, Vieron H. JENNi'Nes, a citizen of the United States, residing at Worcester, in the county of Vforcester and State of Massachusetts, have invented a new and useful Tube Frame for Ax'minster Looms, of which the following is a specilication.

This invention relates to tube frames for AXminster looms, and more particularly to the construction and mounting of the hooked means by which the tube frame is attached to the transporting chain ordinarily found in this type of loom.

The principal object of my invention is to provide a loose pivotal connection between the hook and the bracket so formed that the pressure of supporting the tube frame, whether the latter be right side up or inverted, shall be transferred directly from the hook member to the bracket forming members without the use of pins, small shafts, or other fixed pivotal connections.

A further object of my invention is to provide a bracket formed in two members having associated therewith a rigid hook provided with oifset portions which shall cooperate with the bracket members so that when in one position one of said members will take the strain of supporting the tube frame and when in an inverted position the other member of the bracket will support the tube frame.

A still further object of the invention is to provide a tube frame constructed with a rigid hook having an offset shouldered portion which shall have a loose pivotal connection with the bracket.

With these and other objects in view, which will appear as the description proceeds, my invention resides in the combination and arrangement of parts hereinafter described and set forth in the claims.

In the drawings, wherein one form of my invention is disclosed,

Fig. 1 shows an end elevation of a tube frame constructed according to my invention,

Fig. 2 is a side elevation of the tube frame shown .in .F ig. 1 but withv certain portions shown in vertical section, and

Fig. 3 is a perspective view showing a portion of the hook forming part of my invention.

Serie-.1 No. 683,057.

In the drawings I have shown a hollow metallic tube frame 10 to which are secured in any approved manner the yarn tubes 1,1 as by means of angle member 12. A spool 13 is provided with a gudgeon 14 to be received by the spool bearing member and may be formed as desired..

In carrying out my invention, I provide a spool bearing member 15, the lower end 16 of which extends into and is secured to the upper part of the tube frame 10 by means of screws 17. The upstanding portion of the spool bearing member is arranged to receive the gudgeon 14 and is also provided with a slot 18 which in the form shown in the drawing, preferably extends to the lower end portion 16. Y

The chain engaging member 19 is provided with the usual offset 20 and has leg 21 e2:- tending into the tube frame and secured to the lower part thereof by means of screws 22 and is also provided with a boss 23 for a purpose to be described. As usually constructed, the chain engaging member 19 is provided with a slot for the reception of a hook and in this instance I extend this slot 24, to a point somewhat above the lower end of slot 18 formed in the spool bearing member. The spool bearing and chain engaging members are removably held together by screws 25.

An important feature of my invention relates to the construction of the chain engaging hook and I have shown in the drawings a preferred form which may preferably be made as a drop forging. The hook, shown at 26, is provided with a horizontally eX- tending portion 28 on the under face of which is formed a boss 29 which is preferably located vertically above boss 23. A compression spring 30 is located between the leg 21 and the portion 28 of the hook and is held inplace by bosses 23 and 29, the function of the spring being to hold the head of the hook against the offset portion 2O of the chain engaging member. Y

As shown in Figs. 2 and 3, the body of the hook is provided with an offset portion 81 which defines an upper shoulder 82 and a lower shoulder 38. The offset portion 31 is located in the slots 18 and 24 and is so proportioned as to be slightly less in its vertical dimension than the distance between the upper end of slot 18 and lower end of slot 24.

In Aassembling this structure, the hook 26 is'placed ink slot 24 ofthe chain engaged member with spring 30 in position before being applied to the tube frame. The parts are then moved to the position shown in Fig. 2, the spool bearing member having previously been attached to the tube frame, the upper shoulder 32 lying under the upper end of slot 18. Screws are then passed through the chain engaging member into the spool bearing member. This affords a construction which can be readily assembled or taken apart for repairs.

As shown in Fig. 1 shoulder 32 is in engagement .v with the member 15' while the shoulder 33 is spaced slightly above the bottom of slot 24. In this way the strain of supporting the tube frame from the chain is transferred from the hook to its upper shoulder and from there to the spool bearing member, the horizontal portion 16 of which extendsinto the tube frame and transfers thestrainto the latter independently of screws ,17 or 22. It frequently happens that the tube frame, as it travels through the loom, is in a position inverted from that shown in F ig. 2 and in this position it will be seen that the weight of the tube frame is transferred to the chain by means of the chain engaging member 19, the thrust being taken by leg 21 independently of screws 17 or 22.

Thus it will be seen that I have provided a tube frame construction wherein the chain engagingl hook has a loose pivotal connection with the bracket which is afforded by an offset in thehook lying in aligning slots I y formed in the bracket members, this result being attained without the use of a drilled hole, journals -or other forms of fixed bearing. The offset is so proportioned as to move with freedom in the aligningslots of the bracket members so that itwill respond readily to the actioneither of the spring 30 or the loom actuated disengaging means 1 usual in the type of loom towhich the inyention relates but not shown vin the drawings. y

I-Iaving thus described my invention, it willbe evident that changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention as set forth in the appendedclaims andv I do not lwish to be .otherwise limited tothe details herein disclosed.

What I claiinis: Y

1. In a tube vframe forXminsterlooms, a brackethaving a slot'formed therein and extending lengthwise ofthe vtube-fraine, a hook member associated with the bracket and having an enlarged portion thereof defining upper and vlower shoulders yand located in said slot.. and restrained as torvertical motion by the engagementof saidrshoulders by the ends of said slot, and resilient means for holding said hook in outward position.

2. In a tube frame for AXini-nster looms, a bracket having an opening therethrough extending longitudinal-ly 'of the tube'frame, a hook member associated with the bracket and having an enlarged portion thereon de'- fining a pair of shoulders positioned for engagement with the bracket at the ends of the slot, and resilient means to hold Asaid hook in outward position.

3.' In a tube frame for AXiniiister-looms, a spool bearing member having a slot therein, a `chain engaging member secured there-.

means to hold said hook in outward position.`

4. In a tube frame for Axminsterjlooms, a spool bearing member having a slot formed therein, a chain engaging member having aslot formed therein, portions of said slots being in alignment, a tube frame., member to which said bearing and chain engaging members are secured, the lower end of the slot 1n the outer of the twok members being above the tubevframe, a hook formed with shoulders for engagement with the` spool bearing and chain engaging members and located in thek aligning portions of said slot, and yielding means fto hold lsaid hook outwardly.

Htl

5. In a tube frame for AXminster loomsyj;

a bracket secured to the tube frame and having an opening therethrough extending longitudinally of the tube frame, va hook .inem- -ber having an offset portion'deiiningfshoulders lying in said slot and mounted for-limited vertical motion in said slot, .and yielding means to hold said hook outwardly.

6. In a tube frame for Axininsterrlooms, a bracket formed of two separable parts removably attachedto the frame, said parts having openings therethrough, portionsfof which are in alignment to define a slot through said bracket longitudinally yof the frame, ahook member passing through the slot in said bracket and havingportions, one

to engage 4each of saidparts, to limit verticalmotionfof said hook, and resilientineans to hold said hook outwardly. s
